Fat by Design with its 9 oscillators section, all waveforms but "Sinus" use generalized PWM (called "Ratio"), so you can tune/modulate the waveform of each oscillator / LFO.

Its huge modulations capabilities lets you create a very large sound styles.

The arpeggiator includes an 8 steps sequencer and lets you mute, change the gate duration, the groove and the velocity of each step. In addition, you can use the global Shuffle to humanize your arpeggios. It also sends its notes to MIDI Outs !
